Hello, 

I have modelled a vehicle in Simulink and have successfully controlled it using fuzzy logic control system, 

 I am NOW investigating on how to incorporate friction of the different types of surfaces; such as bumpy roads, sand, paved roads etc.. 
in the model 

I am not sure on how to model these surfaces, I am sure they must include some random signals but can't figure out how to model them 

any ideas? 

your answers are greatly appreciated ! 

thanks ! 

Abdu ,
